How do I get the actual Width of an element such as a Label?
When it's autosized, the Width returns -1, which I can't use to position that label.
The only reason I need to manually position the label is because it's rotated (90 degrees), and since it's more like a RenderTransform than LayoutTransform (from WPF), the built-in layout logic for the rotated Label can't be used. Unless someone knows a trick??
